The 2004 European Parliament election in Sweden was the election of MEP representing Sweden constituency for the 2004-2009 term of the European Parliament. It was part of the wider 2004 European election. The vote took place on 13 June. The ruling Social Democrats polled poorly, but virtually all the established parties lost ground to the eurosceptic June List.

The 2004 European Parliament election was held between 10 and 13 June 2004 in the 25 member states of the European Union, using varying election days according to local custom. The European Parliamental parties could not be voted for, but elected national parties aggregated in European Parliamental parties after the elections.
